Publication of "Caverns of Thracia"
1979
"Caverns of Thracia", published by Judges Guild, is considered one of Jaquays' most influential adventure modules. Its sprawling, multi-layered dungeon, inspired by Greek mythology, diverged sharply from the linear, monster-filled corridors common in early D&D adventures. Its emphasis on exploration, player agency, and challenging encounters solidified her reputation as an innovative designer.
